SH UTTER-FASTENER.

SPECIFICATION forming part of Letters Patent No..342,'792, dated June l. 1886.

Application filed September 9, 1855. Serial No. 176,557. (No model.)

.To all whom it may concern.

Be it known that I, SAMUEL H. HAAs, a citizen of the United States, residing'in Philadelphia, Pennsylvania, have invented certain Improvements in Shutter-Fastenings, of which the following is a specification.

My invention relates to improvements in shutter-fastenings; and the main object of my invention is to construct a device that will 1o combine the bolt, bower, and ring-loops all in one article, and in which the bolt will belocked when projected, as fully described hereinafter.

In the accompanying drawings, Figure 1 is a face view of my improved bolt; Fig. 2, a

section on the line l 2, Fig. l; Fig. 3, a section on the line 3 4, Fig. l; Fig. 4, a plan view showing the two sockets at an angle in respect to each other and lwith the shut-terbower in position; Fig. 5, a detached per- 2o spective view of a part of the fastening, and Fig. 6 a plan view showing how the bolt is inserted in its socket.

A B are the two plates, one secured to each shutter, and having sockets or keepers a and b for the reception and guidance of the sliding bolt D. These plates A B, with their keepers, are cast 'of malleable iron, and have openings x in the rear of the keepers, so that the `castings can be easily drawn from the 3o sand, all cores being dispensed with and the manufacture of the keeper-plates thus materially cheapened and simplified.

The bolt D is prevented from being pulled out by the usual stop, a', cast on the plate.

The plate A, beingmade of malleable iron, can, however, be bent as shown in Fig. 6, in order that the bolt Dmay be inserted into the keepers a c. Then after the end of the bolt has passed the stop a the plate A may be caused 4o to assume its normal fiat or straight form.

. The plateAhas va groove, e, (shown in Figs. 1 and 3,) in which is guided a projection, d', in the back of the downwardly-projectinglug d ofthe bolt. This prevents the usual loose movement of the bolt in the keepers and causes the bolt to move inastraight line, and, consequently, easy to operate.

Projecting downwardly from each plate A B is a loop, E, for the reception ofthe ring G,

5o .and it is provided with guard-fingers f f, to prevent said ring from rubbing against the shutter or door W. Pivoted to one of the plates, and preferably to one of the keepers a, is a shutter-bower, H, Figs. l and 4, which is curved, as shown, and is provided with a series of notches, h, adapted to tit over a stud, i, on one of the keepers, b. Thus the shutters can be bowed to' a greater or less extent, as required.

Projecting from the bower H is a lug,j, adapted to rest on the upper edge of the bolt D when the latter is thrown back, as shown in Fig. 2; but if the shutters are closed and the bolt projected the lug j will drop into a notch, k, in the bolt D, thus locking the bolt and preventing it from 'being forced back with- -out first raising the bower H. The latter thus acts as a locking-latch for the bolt.

I claim as my inventionl. The combination of the sliding bolt and keeperplates with the notched segmental bower pivoted to one of said plates and adapted to engage with a stud on the other plate, substantial] y as described.

2. Akeeper-plate forashutterfastener,hav ing a loop, E, for the reception of aloose ring, G, substantially as set forth.

3. A keeper-plate for ashutterfastener,hav

ing a loop, E, for the reception ofa ring, and having guard-fingersf, as set forth.

- 4, A keeper-plate having keepers a and a stop, a', cast integral with the plate, of malleable cast-iron, wherebythe keeper-plate can be bent for the insertion of the bolt, 'substantially as specified.

5. The combination of the bolt having a projection, d', with a keeper-plate having aA groove, e, for the reception and guidance of said lug, substantially as specied.

6. The combination of the keeper-plate B, having a stud, t', with the sliding boit having a notch, lc, and the keeper-plate A, having a pivoted bower provided with a lug adapted to said notch in the bolt, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

SAMUEL H. HAAS.
